Milling & rotary-table work
Vertical milling produces flat faces, slots, grooves, pockets, and profiles. Rotary-table setups position the work for circular features and features spaced around a part.
Machining & tool-room support
Milling, turning
& surface grinding.
From a machined component to the tooling that makes it, K-O brings milling, turning, drilling, boring, reaming, tapping, threading, and surface grinding into your manufacturing plan. Connect the work with stamping, welding, finishing, and assembly in Benton Harbor, Michigan.
Machining services
The right operation
for each feature.
Machining removes material to create the surfaces and features that determine how a part fits, fastens, or moves. Our tool room supports component machining, prototypes, fixtures, and tool maintenance and repair.
We plan each setup around the drawing, material, and features that need to stay in alignment. That can mean machining a part from stock or adding details to a component made through another K-O process.
Turning & threading
Lathe operations shape round stock into diameters, shoulders, faces, and grooves. Threading adds fastening features, while facing and chamfering prepare ends for mating parts or the next operation.
Drilling, boring & reaming
Drilling creates holes. Boring enlarges and trues an existing hole; reaming brings a prepared hole to its specified size and finish. Tapping adds internal threads for fasteners and mating components.
Surface grinding
Surface grinding finishes flat faces on parts, tooling, and fixtures. The wheel removes small amounts of material to bring the surface to its specified dimension and finish.
Sawing & blank preparation
Horizontal and vertical bandsaws and chop-saw cutting prepare stock and blanks for machining. The cutting plan allows for the material that later operations will remove.
Deburring & edge finishing
Belt sanding and bench grinding remove burrs and dress edges where the part calls for it. Edge preparation helps components move into handling, welding, finishing, or assembly.
Tool-room working capacities
Start with the size.
Plan around the part.
Use these dimensions as a starting point for your inquiry. We review part height and length, workholding, tool access, material, and tolerances to confirm the setup for your drawing.
| Process | Working size | Setup capability |
|---|---|---|
| Vertical milling | 32 × 16 intable travel | Rotary-table setups available for positioning and circular work. |
| Turning | Up to 14 instock diameter | Engine-lathe work; include the part length and any features requiring support. |
| Surface grinding | 12 × 24 inlargest working envelope | Additional 6 × 18 in working envelopes and grinding fixtures. |
| Drilling | Up to 4 inhole diameter | Radial-drill capability; material, hole depth, and workholding determine the setup. |
Tolerances follow your drawing.
Include the required dimensional tolerances, flatness, surface finish, and inspection criteria. We confirm achievable requirements with the material and setup during quotation.
How we make your part
A manufacturing plan
that carries through.
A hole location, ground face, or threaded end often affects the next operation. We consider those relationships from the start so machining supports the finished component or assembly.
Define the part & setup
Review the drawing revision, material condition, quantities, and critical features. Establish locating surfaces and workholding so the part can be positioned consistently through its machining steps.
Sequence the operations
Prepare the blank, then plan milling, turning, hole-making, threading, and grinding in the order the part needs. Account for stock removal and any later welding, heat treatment, or finishing that can affect final dimensions.
Check & complete
Check the agreed dimensions and feature relationships before the part moves onward. Connect machining with finishing, assembly, inspection records, and protective packaging for delivery.
From cut stock to a locking-pin assembly.
K-O’s locking-pin project shows how machining and assembly work together. Several operations produced the features needed for the final fit.
Explore the locking-pin case study- The pin was cut to length and chamfered in a turret lathe.
- A groove was milled, and holes were drilled and chamfered.
- The collar was cut, drilled, and chamfered before final assembly.

A few useful answers
Before you
send the inquiry.
What machining operations does K-O offer?
Milling, turning, drilling, boring, reaming, tapping, threading, surface grinding, sawing, and edge finishing. Rotary tables support positioning and circular milling work. We review the combination of operations around your component or tooling requirement.
Do the working capacities tell me the largest part you can make?
They give a starting point. Milling travel and grinding envelopes describe machine movement or working area. Actual part size also depends on height, length, fixtures, tool access, and the features to be machined. Send the drawing for a setup review.
Is surface grinding the same as centerless bar grinding?
Surface grinding finishes flat surfaces on components and tooling. Centerless bar grinding finishes the outside diameter of round bar. K-O offers both; the part geometry and drawing determine which process fits.
Can machining be combined with other K-O services?
Yes. Machining can be part of a program that includes stamping, bar processing, welding, finishing, assembly, and kitting. Include the complete delivered-part requirement so we can plan the sequence and inspection points together.
